具体以源码为准 Talent继承自Marionette继承自BackBone Region: 继承自Backbone.Event,show(view)会调用view.render(),然后$el.append(view.el),触发相应的事件 Layout: 继承自 ItemView,可以设置regions属性 CompositeView: 继承自collectionView,将Item添加到template中 'itemview:deleteItem'事件 itemViewOptions Co…

/* L (>=60), the lower bound of the qualified grades -- that is, only the ones whose grades of talent and virtue are both not below this line will be ranked; and H (<100), the higher line of qualification ,those with both grades not below this line…

难得的一次ac 题目意思直接,方法就是对virtue talent得分进行判断其归属类型,用0 1 2 3 4 表示 不合格 sage noblemen foolmen foolmen 再对序列进行排序 优先级  类型>total grade>virtue>id #include<iostream> #include<stdio.h> #include<string.h> #include<algorithm> using namespac…

1. 在排序的过程中,注意边界的处理(小于.小于等于) 2. 对于B-level,这题是比較麻烦一些了. 源代码: #include <cstdio> #include <vector> #include <algorithm> using namespace std; struct People { int m_id; int m_virtue; int m_talent; People(int id, int virtue, int talent): m_id(id…

分数规划是这样一个东西: 给定若干元素,每个元素有两个属性值\(a_i,b_i\),在满足题目要求的某些限制下选择若干元素并求出\(\frac{\sum a}{\sum b}\)的最大值. 如果没有限制的话,肯定是贪心的选. 假设当前选择了一个解\(x_0\),却并不是\(\frac{\sum a}{\sum b}\)的最大值,我们有 \[\frac{\sum a}{\sum b}>x_0\] 进而 \[\sum a-bx_0>0\] 这时候我们要求的东西变成了\(a-bx_0\),每个元素的…
